Ecology: This is probably the smallest of the hammerhead species, residing on the continental shelf in inshore habitats . It is born at around 23 cm total (TL ); males are mature at approximately 67 cm TL; and the species reaches a maximum size of approximately 92 cm TL. Uncommonly seen; biological information is lacking; and fecundity is low, with a noted litter size of two (Compagno 1984).
